Japanese Navy 1st Class Seamanship Badge
From the excellent website “Imperial Japan Medals and Badges” dot com: “Awarded to NCOs who operated piloting of warships and submarines. The test consisted of compass reading, the methods of piloting different kinds of ships, the targeting of enemy ships, maneuvering strategies, etc.” The badge is in excellent condition with fine enamel and dark, uncleaned patina. It is contained within its fitted, titled leather case, which shows expected signs of age and wear. The gilt kanji on the lid is worn, but the impressed letters remain visible.
